Methods of testing and sorting integrated circuits in clusters are disclosed. Each cluster has power and data terminals connected to common power and data busses providing a common power supply. Each integrated circuit has a first non-volatile memory storing an activation code and a second programmable non-volatile memory that is capable of storing the activation code. If an integrated circuit passes testing, the activation code stored in the first non-volatile memory is written into the second ...

In an A/D converter, isolation switches are used between the capacitors and the conversion switches. The conversion switches are those switches used to selectively couple the plates of the binary weighted capacitors to either Vref or 0 volts during the A/D conversion process. During sampling of the input voltage signal, the isolation switches are opened to isolate the conversion switches from the wide range of possible input voltages at the bottom plates of the capacitors. Therefore, the ...
